[PATCH V4] virtio-fs: Improved request latencies when Virtio queue is full
...moved return value on error changes to simplify patch,
that should be changed in another patch.
V3: Fixed requests falling into the void when -ENOMEM and no new
incoming requests. Virtio-fs now always lets -ENOMEM bubble up to
userspace. Also made queue full condition more explicit with
-ENOSPC in `send_forget_request`.
V2: Not scheduling dispatch work anymore when not needed
and changed delayed_work structs to work_struct structs

[PATCH 0/3] virtiofs: Small Cleanups for 5.5
Hi Miklos,
Here are few small cleanups for virtiofs for 5.5. I had received some
comments from Michael Tsirkin on original virtiofs patches and these
cleanups are result of these comments.
Thanks
Vivek

virtiofs: Use a common function to send forget
virtiofs: Do not send forget request "struct list_head" element
virtiofs: Use completions while waiting for queue
